Yes you are correct. Let me revamp my statement. They changed the formula to support DA and random orbitals. Originally it could only be used with rotary buffers. It's chemically similar but added non-diminishing abrasives to reduce the need for the high speed passes to achieve the same result. Then M205 was introduced in 2009 as a complimentary product to refine the 1200git removal produced left by the 105. It's also a 4 grade cut that can be used as for swirl removal or light correction. And might I add it does one heck of a job. Those two items and a WAX of your choice delivers a sensational end result.
